How do the earths physical features affect people activities

I think it's recreational activities, method of transportation, and choice of occupation. So all of the above. Why? So lets start with recreational activities. Earth's physical form depends of if people want to go fishing, hiking, hiking, etc. Method of transportation. We need to have smooth ground to bike or drive on. A highway isn't going to be in the middle of the mountain. We need to have a good solid surface. Choice of occupation. Earth has a physical feature of like I said, mountains, plains, oceans, etc. We want to live in a place that has good resources, and good weather. All of these things depend on physical features of Earth.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust. 

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
